Recording Movies
Flicker, banding, or distortion may be visible in the monitor and in the
final movie under fluorescent, mercury vapor, or sodium lamps or with
subjects that are in motion, particularly if the camera is panned
horizontally or an object moves horizontally at high speed through
frame (for information on reducing flicker and banding, see Flicker
reduction; 0 213). Jagged edges, color fringing, moire, and bright
spots may also appear. Bright regions or bands may appear in some
areas of the frame with flashing signs and other intermittent light
sources or if the subject is briefly illuminated by a strobe or other
bright, momentary light source. Avoid pointing the camera at the sun
or other strong light sources. Failure to observe this precaution could
result in damage to the camera's internal circuitry.
The camera can record both video and sound; do not cover the
microphone during recording. Note that the built-in microphone may
record lens noise during autofocus and vibration reduction.
Flash lighting can not be used during movie recording.
Matrix metering is used regardless of the metering method selected.
Shutter speed and ISO sensitivity are adjusted automatically unless On
is selected for Manual movie settings (0 142) and the camera is in
mode M.
